Creating an API with Ruby on Rails is simple and quick. The nature of Ruby allows it to use external services easily, which is why it is a great idea to develop an API using Ruby on Rails.

When a developer says that they are using Rails as the API, it indicates that they are using Ruby on Rails Development to build the backend, which is shared between the web application and native applications. Let’s see how you can develop an API using RoR.

What is Ruby on Rails?

The best part about Ruby on Rails is that it is open-source software. Users can utilize Ruby on Rails to develop applications or collaborate to bring change to their code.

Ruby on Rails focuses on opting for convention rather than configurations and optimized systems for programmers. Ruby on Rails works excellently with other technologies like Java, CSS, and HTML.

Example: Ruby on Rails API Development Steps

Step 1: API creation using Rails

To initiate the creation of an API, one must first write the below-written code in the terminal of any chosen directory. Using the code written below will create an API named secret_menu_api

$ rails <span class="token keyword keyword-new" style="box-sizing: border-box; color: rgb(0, 119, 170);">new</span> secret_menu_api –<span class="token operator" style="box-sizing: border-box; color: rgb(154, 110, 58); background: rgba(255, 255, 255, 0.5);">-</span>api <span class="token operator" style="box-sizing: border-box; color: rgb(154, 110, 58); background: rgba(255, 255, 255, 0.5);">-</span><span class="token operator" style="box-sizing: border-box; color: rgb(154, 110, 58); background: rgba(255, 255, 255, 0.5);">-</span>database<span class="token operator" style="box-sizing: border-box; color: rgb(154, 110, 58); background: rgba(255, 255, 255, 0.5);">=</span>postgresql

$ rails <span class="token keyword keyword-new" style="box-sizing: border-box; color: rgb(0, 119, 170);">new</span> secret_menu_api –<span class="token operator" style="box-sizing: border-box; color: rgb(154, 110, 58); background: rgba(255, 255, 255, 0.5);">-</span>api <span class="token operator" style="box-sizing: border-box; color: rgb(154, 110, 58); background: rgba(255, 255, 255, 0.5);">-</span><span class="token operator" style="box-sizing: border-box; color: rgb(154, 110, 58); background: rgba(255, 255, 255, 0.5);">-</span>database<span class="token operator" style="box-sizing: border-box; color: rgb(154, 110, 58); background: rgba(255, 255, 255, 0.5);">=</span>postgresql

$ rails <span class="token keyword keyword-new" style="box-sizing: border-box; color: rgb(0, 119, 170);">new</span> secret_menu_api –<span class="token operator" style="box-sizing: border-box; color: rgb(154, 110, 58); background: rgba(255, 255, 255, 0.5);">-</span>api <span class="token operator" style="box-sizing: border-box; color: rgb(154, 110, 58); background: rgba(255, 255, 255, 0.5);">-</span><span class="token operator" style="box-sizing: border-box; color: rgb(154, 110, 58); background: rgba(255, 255, 255, 0.5);">-</span>database<span class="token operator" style="box-sizing: border-box; color: rgb(154, 110, 58); background: rgba(255, 255, 255, 0.5);">=</span>postgresql

You must type the below-written code in the terminal to open the API menu.

$ cd secret_menu_api code

$ cd secret_menu_api code

$ cd secret_menu_api code

Step 2: Enabling CORS (Cross-Origin Resource Sharing)

CORS enables other people to access the API. To prevent other people from accessing the API, one can disable the CORS. To open the cors.rb file, you need to open the file explorer where the Rails API created now is present.

config <span class="token operator" style="box-sizing: border-box; color: rgb(154, 110, 58); background: rgba(255, 255, 255, 0.5);">&gt;</span> initializers <span class="token operator" style="box-sizing: border-box; color: rgb(154, 110, 58); background: rgba(255, 255, 255, 0.5);">&gt;</span> cors<span class="token punctuation" style="box-sizing: border-box; color: rgb(153, 153, 153);">.</span>rb

config <span class="token operator" style="box-sizing: border-box; color: rgb(154, 110, 58); background: rgba(255, 255, 255, 0.5);">&gt;</span> initializers <span class="token operator" style="box-sizing: border-box; color: rgb(154, 110, 58); background: rgba(255, 255, 255, 0.5);">&gt;</span> cors<span class="token punctuation" style="box-sizing: border-box; color: rgb(153, 153, 153);">.</span>rb

config <span class="token operator" style="box-sizing: border-box; color: rgb(154, 110, 58); background: rgba(255, 255, 255, 0.5);">&gt;</span> initializers <span class="token operator" style="box-sizing: border-box; color: rgb(154, 110, 58); background: rgba(255, 255, 255, 0.5);">&gt;</span> cors<span class="token punctuation" style="box-sizing: border-box; color: rgb(153, 153, 153);">.</span>rb

You must uncomment the lines and change the code from origins ‘example.com’ to origins’*’.

$ rails g resource Post title description

$ rails g resource Post title description

After using the command, it will then generate the below-mentioned files.

Step 5: Defining display, index, destroy, update, and create actions.

Here are the implications of the actions:

Index: It will display all the posts present in the database.
Show: It will display the specific(given as an id) post.
Create: It will make the post’s instance.
Update: It will update the post-item instance.
Delete: It will delete specific post items.

Now copy and then paste the below code in secret_menu_intems_controller.rb.Now let’s write API magic over here.

Step 6: Creating routes for index, create, show, delete, and update actions.

Routes receive HTTP requests that come from the client side. We have to forward it using the correct actions. To configure the route, copy the following code and paste it into the route.rb.
